Answer:
Choice D
Step-by-step explanation:
The distance increases at a steady rate from time = 0 to time = 1.
Then no progress is made between time = 1 and time = 2.
Then the distance increases at the same steady rate from time =2 to time = 3.
Finally, no progress is made between time = 3 and the end of the graph.
Eliminate Choices A, B and C immediately, because none of these scenarios involves a stop and wait.
That leaves only Choice D as a reasonable verbal description of what's happening here.
Answer:
Answer a: mST=20
Answer b: mST=48
Step-by-step explanation:
Problem a:
3a-5=2a+50
a=55
2(55)+50=160
180-160=20
Problem b:
180=4c-12
192=4c
48=c
